The 807 Beam Tetrode...

A little bit on the good old 807...

Still I remember I saw a grampian P A amplifier 30 w in 1979 with 807 power output ecc 83 driver and EF 86 preamp

If 4 tubes in parallel, how much watts we can take ?

Yeah you have started something good Steve, now show us the psu with screen and -30 v , i still have some 807's but for all that work ...jeez, run a 4cx250 then , and gain some more advantage, i mean qrp is fun and all, but 400 watts is more fun in a short period of time :)
